How do you find a fossil's absolute age? The absolute age (or direct dating) of a fossil is determined by knowing the age of the surrounding rock. The most common way is by radiometric dating, a method that relies on the natural radioactivity of certain elemental isotopes. Different isotopic elements-such as uranium, rubidium, argon, and carbon-have varying (but constant) rates of radioactive decay. This constancy provides a "radiometric clock," allowing scientists to analyze rock samples and measure the relative ratios between the "parent" and "daughter" isotopes. The ratios reveal the age of the rock layer, and thus, the age of the associated fossil. As with many scientific measurements, although the method is called "absolute," the dates are not exact and there is room for potential errors.

Geologists determine absolute age by using radiometric dating techniques that involve measuring the decay of radioactive isotopes in rocks or minerals. By analyzing the ratio of parent isotopes to daughter isotopes in a sample, geologists can calculate the absolute age of the rock formation. This method provides a numerical age in years for the rock layer or mineral.
The specific age of a rock or fossil can be determined through radiometric dating techniques, such as carbon dating or uranium-lead dating. These methods measure the amount of radioactive isotopes present in the sample to calculate its age. Additionally, stratigraphic dating can be used to determine the relative age of rocks and fossils based on their position in layers of sedimentary rock.

The absolute age of a fossil provides a specific numerical age in years, usually determined through radiometric dating techniques. Relative age, on the other hand, only allows us to determine the fossil's age in relation to other fossils or rocks, based on their layering or sequence in the rock record.
You can determine the relative age of a fossil by looking at the position of the fossil in the rock layers. The closer a fossil is to the surface, the younger it is relative to fossils found deeper in the layers. To determine the absolute age of a fossil, scientists use radiometric dating techniques on the surrounding rocks to determine the age of the rock layer the fossil is found in.

Scientists can use carbon dating to determine the age of a fossil.
It depends. If you are comparing it to something then it is relative. But if your give it a specific age/year, then it is absolute. ex. Relative: The fossil is younger than the shale. Absolute: The fossils is 1000 years old. *note; even if the age is wrong it would still be classified as absolute time
scientist can determine a fossil's age in two ways: relative dating and absolute dating
By using radiometric or radiocarbon dating.
There are two methods used to determine the age of a rock or fossil. The first is carbon dating and the second is radiometric dating.
